If your RO (RO/DI) system is constantly turning on to make up a small amount of top off water, then you are going thru DI resin faster than you should be!

TDS Creep is a phenomenon is which the TDS out of an RO membrane is a very HIGH value vs. the TDS that the user will see in as little as 30 seconds after the system begins to make water.

RO Membranes all experience TDS creep upon startup, every single time they start up - so reducing the amount of "start-stops" that an RO system experiences will directly translate to longer lasting DI resin.

Reduce TDS creep and SAVE BIG money on DI Resin with the AquaFX dual float "creep killer" storage tank. Available in 100 gal upon request. This tank can pay for its self in as little as 7 months!

Simply put - the tank uses 2 floats and a 110v solenoid to control the flow out of or into the RO/DI system. The solenoid will close when both floats are "up" - then the solenoid will only open once the bottom float falls.

This storage tank arrives fully assembled and ready to install. I connected mine to my Barracuda RO/DI with Chloramine Blaster add on and it works like a charm. As advertised, it only calls for water refill when the lower sensor activates the solenoid and stop the production of RO/DI water when the upper level sensor is reached. Very efficient, worry free, and keeps out unwanted "creep".

Q:What does this do other than store water with a float? How does it save DI? Thanks!

A:Hey Michelle - Great Question - so every single time your RO membrane turns on it experiences TDS creep .... TDS Creep = a high value of TDS. Also, RO membranes will find their peak efficiency after a long run time (ie they will reject more % TDS) - So how will this allow DI to last longer? By #1) Limiting the number of times TDS creep will happen - not allowing the RO/DI system to turn on every time it needs to make a drop of water or even a cup (small volumes) #2) By allowing the RO membrane to make larger volumes of water at a time, this again is where RO membranes shine with TDS rejection. - This all will directly translate into longer lasting DI resin :)
